Two Duos with Gerry

The drummer and composer Gerry Hemingway has played his share of expressionistic duo improvisations, including the one that yielded a recent four-CD release with the multireedist Anthony Braxton, “Old Dogs (2007).” For this performance Mr. Hemingway squares off with a pianist, Russ Lossing, at 8:30 p.m., followed by a guitarist, Terrence McManus, at 9:30.
